"benefits": "NASA is using several manufacturing processes supporting the Space Launch System to create structures with superior mechanical properties and increased reliability. Solid state welding including ultrasonic, thermal, and friction stir welding is among the joining methods particularly well suited for high-strength, temperature-resistant materials such as titanium alloys, Inconel/Nickel-Based alloys. Real-time, in-process measurement of weld temperature can be used to control the joining process to produce high-strength, defect-free components and joints, improve weld quality, significantly reduce costs, and increase production rates. Potential NASA applications for the TSW technology include solid and liquid rocket motor casing, liquid rocket nozzle extensions, and other high temperature components.
